Hypertension is a major risk factor for cardiovascular disease (CVD), but previous studies have mostly been limited to a single exam, a single cohort, a short follow-up period, or a limited number of outcomes. This study aimed to assess the association of 10-year cumulative systolic blood pressure (BP) in middle age with long-term risk of any CVD, coronary heart disease, stroke, heart failure, all-cause mortality, and healthy longevity. Individuals (11 502) from 5 racially/ethnically diverse US community-based cohorts were included in this study once they met all the inclusion criteria: ≥10 year of observation in the included cohort, aged 45 to 60 years, free of CVD, and had ≥3 visits with BP exams over the preceding 10 years. For each participant, systolic BP level was predicted for each year of the 10-year prior inclusion, based on the available exams (median of 4.0; spread over, 9.1 [range, 7.2-10] years). Lower 10-year cumulative systolic BP was associated with 4.1 years longer survival and 5.4 years later onset of CVD, resulting in living longer life with a shorter period with morbidity. Models adjusted for sociodemographic characteristics, cardiovascular risk factors, and index systolic BP demonstrated associations of 10-year cumulative systolic BP (per 130 mm Hg×year change, the threshold for stage-1 hypertension) with CVD (hazard ratio [HR], 1.28 [95% CI, 1.20-1.36]), coronary heart disease (HR, 1.29 [95% CI, 1.19-1.40]), stroke (HR, 1.33 [95% CI, 1.20-1.47]), heart failure (HR, 1.12 [95% CI, 1.02-1.23]), and all-cause mortality (HR, 1.21 [95% CI, 1.14-1.29]). These findings emphasize the importance of 10-year cumulative systolic BP as a risk factor to CVD, above and beyond current systolic BP.
高血压是心血管疾病(CVD)的一个主要危险因素,但以前的研究大多仅限于单次检查、单个队列、短期随访或有限的结果。本研究旨在评估中年时 10 年累计收缩压(BP)与长期 CVD、冠心病、中风、心力衰竭、全因死亡率和健康长寿的风险之间的关系。本研究纳入了来自 5 个美国基于社区的种族/民族多样化队列的个体(11502 人),只要符合所有纳入标准,就会进行一次研究:在纳入的队列中观察≥10 年,年龄 45 至 60 岁,无 CVD,并且在过去 10 年中有≥3 次血压检查。对于每个参与者,根据可用的检查结果(中位数为 4.0;分布在 9.1[范围为 7.2-10]年内),预测 10 年前纳入期间每年的收缩压水平。较低的 10 年累计收缩压与 4.1 年的生存时间延长和 5.4 年的 CVD 发病时间延迟相关,从而在较短的发病时间内延长了更长的健康寿命。调整了社会人口统计学特征、心血管危险因素和指数收缩压的模型显示,10 年累计收缩压(每 130mmHg×年变化,高血压 1 期的阈值)与 CVD(风险比[HR],1.28[95%置信区间,1.20-1.36])、冠心病(HR,1.29[95%置信区间,1.19-1.40])、中风(HR,1.33[95%置信区间,1.20-1.47])、心力衰竭(HR,1.12[95%置信区间,1.02-1.23])和全因死亡率(HR,1.21[95%置信区间,1.14-1.29])相关。这些发现强调了 10 年累计收缩压作为 CVD 风险因素的重要性,超过了目前的收缩压。
